A trustfunder who pretends he/she is poor by taking on what he/she perceives as downmarket accoutrements, lingo, etc. Goes beyond "slumming it," as the appearance/manner/speech matches the environment in which the "slumming" plays out. In extreme cases, may manifest itself as a street musician playing for change, a runaway sleeping in doorways, or Muffy the stripper.

Usually a phase in which apathetic and/or nihilistic rich kids indulge themselves until Daddy or Mummy snaps them out of it with a threat to disinherit/cut off funds.

A fake bohemian. Someone who dresses in attire typical to the bohemian lifestyle; someone who purposefully assumes the appearance of being nontraditional, artsy, and/or poor, but does so for fashion or personal appearance purposes only.

Wow, that guy in the Porsche with the flannel plaid shirt, horn-rimmed glasses, torn jeans, and beaten-up converse tennis shoes is such a fauxbo.
